Q21 When healthy people overeat a few, what does it become? A In this case, they should become sleepy. However, the matter same as unhealthy people happens. It is not the proof with healthy them that they become sleepy after a meal. Why does it become sleepy in that case? Because, other functions are stopped in order to make the function of the body devoted to digestive activities. And energy is stored up inside of the body. If it is healthy people after sleepiness goes away, they want to become fine and to come to move the body. Because, the body itself tends to make it exhaust quickly and it tends to return overmuch energy normally. After sleepiness goes away, those who do not become fine have to think that abnormalities are in the body.
